What part of the 6,000 mile service is really necessary? Will the valves need adjustment or does it just amount to a"clearance check"? If I can do some of it, will the dealer do piece meal portions of the 6K mile "service"? The final drive has a drain plug but no fill plug(brilliant), how does one manage to get the 180cc of super duper ultra mega lube in there? If I have to ride 90 miles to the dealer, how can they check cold valve clearance on the same day? I don't do things half-a$$ed so would that mean a sleep over? Is the dealer service stamp for this in the owners manual an important documentation for a future owner? Thanks guys!
